' DOOR-SECURER.

SPECIFICATION forming part of Letters Patent No. 308,823, dated December 2, 1884.

Application filed March 21, 1884. (Model.)

To a/ZZ whom, t may concern:

Be it known that I, WILLIAM J. BITTER, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Irnprovements in Door-Locks, of which the following is a specification.

This invention relates to improvements in that class of devices for fastening doors in which a bar is provided at one end with spurs and a ratchet, the other end being pivoted to one extremity of a li`nk,tl1e other end of which link is pivoted to a pawl having a free end adapted to engage and disengage the ratchet on the bar, the link having a lip at its lower end projecting at right angles in line with the bar to pass under the door.

The object of my invention is to simplify such devices, and render them practically useful without the necessity of employing the ratchet-bar or the pawl pivoted to the lipped link; and to such end my invention consists in the novel construction and arrangement of devices hereinafter described and claimed, reference being had to the accompanying drawing, in which the ligure is Va perspective View of my improved fastener in position to fasten a door, a part ol' the latter being shown by dotted lines.

In the drawing, A indicates a rectilinear metallic bar having at one end a pointed projection, D, (one or more) and at the other two separated ears having perforations for the passage of a pintle or pin. The plate B is formed at its lower end with a flange, E, eX- tending at right angles to the plate, and on the back of the plate, centrally between the ends and sides of the same, is formed a projecting stud, F, having a perforation entering between I the ears on the bar, and loosely held therein by the pintle or pin. The fastener is applied by placing the flange E under the door between it and the oor I, and then crowding the plate B up against the inner side of the door and forcing the spur or spurs D of the bar A into the door. By the central arrangement of the connection on the angleplate B with the bar A when the door is secured any pressure thereon .will be received bodily by the plate, and resisted in a straight line from the center of the plateby the bar, and,further, the upper end of the plate cannot be tilted back, owing to its being rigidly sustained by its connection with the bar, and, further, by reason of the iange abutting against the lower edge of the door. The arrangement is suoli that the pivot pin and bar afford a central fulcru1n,which will resist any pressure on the plate, so that the latter cannot be thrust rearward at its upper end; and by this means I am enabled to avoid the use of a pawl to engage a ratchet on the bar for sustaining the upper end of the angleplate against inward pressure or thrusts.

Having thus described my invention, what I claim isy A door-fastener consisting of the bar A,hav ing the spur D, and the fianged plate B, piv oted centrally between its upper and lower ends to the bar, substantially as and for the purpose described.

ln testimony whereof Iliave hereunto set my hand in the presence of two subscribing witnesses.
